EBV is a human gamma-herpesvirus that infects over 90% of the adultpopulation worldwide [Young, L. S. and A. B. Rickinson, Epstein-Barrvirus: 40 years on, Nat. Rev. Cancer, 2004, 4:757-68; Rickinson, A. B.and E. Kieff, Epstein-Barr Virus, in Fields Virology, Third Edition,1996, Lippincott-Raven Publishers, pp. 2397-446]. In combination withknown and unknown cofactors, especially immunosuppression, EBV infectionconstitutes a high carcinogenic risk. EBV has been classified by theWorld Health Organization as a class I human carcinogen because of itscausal association with Burkitt's lymphoma, nasopharyngeal carcinoma,50% of all Hodgkin's lymphoma, gastric carcinoma, angiocentric T/NKlymphoma, and lymphoproliferative disorders of the immunosuppressed. Ithas been estimated that EBV is responsible for 1% of all human cancersworldwide [Parkin, D. M., F. Bray, J. Ferlay, and P. Pisani (2005)Global Cancer Statistics, 2002, Cancer J. Clin. 55:75-108]. Theoncogenic potential of EBV is readily demonstrated in vitro by itscapacity to immortalize primary B-lymphocytes in culture and in vivo byits ability to drive infected B-cells into aggressive lymphoblasticlymphomas in immunocompromised hosts.

EBV, like other herpesviruses, has a latent and lytic replication cycle.While the EBV lytic cycle is essential for viral transmission andincreases risk of EBV-associated malignancy, it is the latent viralinfection that is oncogenic [Thorley-Lawson, D. A. and A. Gross,Persistence of the Epstein-Barr virus and the origins of associatedlymphomas, N. Engl. J. Med., 2004. 350:1328-37]. The latent virusexpresses a limited set of viral genes that stimulate cellularproliferation and survival. Clinically available inhibitors ofherpesvirus DNA polymerases, including variants of acyclovir (e.g.ganciclovir) and phosphonoacetic acid (e.g. foscarnet), have at leastpartial inhibitory activity against EBV lytic replication. However, noneof the available herpesvirus antivirals are effective at blocking thevirus from progressing to a latent infection or eliminating latentinfection. Primary infections with EBV can evoke a robust, sometimesdebilitating, immune response referred to as infectious mononucleosis(IM) [Vetsika, E. K. and M. Callan, Infectious mononucleosis andEpstein-Barr virus, Expert Rev. Mol. Med., 2004. 6:1-16]. Despite thisrobust immune reaction, the virus efficiently establishes latentinfection in B-lymphocytes, where the virus can reside in long-livedmemory B-cells [Babcock, G. J., L. L. Decker, M. Volk, and D. A.Thorley-Lawson, EBV persistence in memory B cells in vivo, Immunity,1998, 9:395-404]. In some circumstances, latent infection can also beestablished in T-lymphocytes and epithelial cells. During latency, thevirus does not produce infectious particles, and viral gene expressionis limited to a subset of transcripts with growth-transforming andanti-apoptotic functions that contribute to EBV carcinogenesis. Thus, noexisting anti-viral drug or immunological response can block theestablishment of an EBV latent infection, which has the potential todrive lymphoid and epithelial cell oncogenic growth transformation.

Numerous studies have demonstrated that Epstein-Barr Nuclear Antigen 1(EBNA1) is an ideal target for elimination of latent infection andtreatment of EBV-associated disease. First, EBNA1 is expressed in allEBV-positive tumors [Leight, E. R. and B. Sugden, EBNA-1: a proteinpivotal to latent infection by Epstein-Barr virus, Rev. Med. Virol.,2000, 10:83-100; Altmann, M., D. Pich, R. Ruiss, J. Wang, B. Sugden, andW. Hammerschmidt, Transcriptional activation by EBV nuclear antigen 1 isessential for the expression of EBV's transforming genes, Proc. Natl.Acad. Sci. USA, 2006, 103:14188-93]. Second, EBNA1 is required forimmortalization of primary B-lymphocytes and for the stable maintenanceof the EBV genome in latently infected cells [Humme, S., G. Reisbach, R.Feederle, H. J. Delecluse, K. Bousset, W. Hammerschmidt, and A.Schepers, The EBV nuclear antigen 1 (EBNA1) enhances B cellimmortalization several thousand-fold, Proc. Natl. Acad. Sci. USA, 2003,100:10989-94]. Third, genetic disruption of EBNA1 blocks the ability ofEBV to immortalize primary human B-lymphocytes and causes loss of cellviability in previously established EBV-positive cell lines [Lee, M. A.,M. E. Diamond, and J. L. Yates, Genetic evidence that EBNA-1 is neededfor efficient, stable latent infection by Epstein-Barr virus, J. Virol.,1999. 73:2974-82]. Fourth, biochemical disruption of EBNA1 foldingblocks the establishment of EBV latent infection. HSP90 inhibitors causethe selective killing of EBV⁺ B-cells and block lymphomagenesis in mousemodels [Sun, X., E. A. Barlow, S. Ma S. R. Hagemeier, S. J. Duellman, R.R. Burgess, J. Tellam, R. Khanna, and S. C. Kenney, 2010, Hsp90inhibitors block outgrowth of EBV-infected malignant cells in vitro andin vivo through an EBNA1-dependent mechanism, Proc. Natl. Acad. Sci.USA, 107:3146-51]. Fifth, EBNA1 is a noncellular viral oncoprotein thatis functionally and structurally well characterized. Thethree-dimensional structure of EBNA1 bound to its cognate DNA sequencehas been solved by X-ray crystallography [Bochkarev, A., J. A. Barwell,R. A. Pfuetzner, E. Bochkareva, L. Frappier, and A. M. Edwards, Crystalstructure of the DNA-binding domain of the Epstein-Barr virusorigin-binding protein, EBNA1, bound to DNA, Cell, 1996, 84:791-800;Bochkarev, A., J. A. Barwell, R. A. Pfuetzner, W. Furey, A. M. Edwards,and L. Frappier, Crystal structure of the DNA binding domain of theEpstein-Barr virus origin binding protein EBNA-1, Cell, 1995, 83:39-46;Bochkarev A, Bochkareva E, Frappier L, Edwards A M. The 2.2 Å structureof a permanganate-sensitive DNA site bound by the Epstein-Barr virusorigin binding protein, EBNA1. J Mol Biol, 1998. 284:1273-78]. Analysisof the DNA binding domain reveals that EBNA1 protein is druggable, withseveral deep pockets and channels within the DNA binding domain that arepredicted to disrupt DNA binding when bound to small molecules. Sixth,targeting a non-self viral-encoded protein for inhibition mitigates thepotential risk of inherent toxicity. EBNA1 has a unique structural foldthat is distinct from all known cellular DNA binding and replicationproteins [Sun X, Barlow E A, Ma S, Hagemeier S R, Duellman S J, BurgessR R, Tellam J, Khanna R, Kenney S C. (2010) Hsp90 inhibitors blockoutgrowth of EBV-infected malignant cells in vitro and in vivo throughan EBNA1-dependent mechanism. Proc Natl Acad Sci USA 107:3146-51;Bochkarev A, Barwell J A, Pfuetzner R A, Bochkareva E, Frappier L,Edwards A M. Crystal structure of the DNA-binding domain of theEpstein-Barr virus origin-binding protein, EBNA1, bound to DNA. Cell,1996. 84:791-800; Bochkarev A, Barwell J A, Pfuetzner R A, Furey W,Edwards A M, Frappier L. Crystal structure of the DNA binding domain ofthe Epstein-Barr virus origin binding protein EBNA-1. Cell, 1995.83:39-46]. Finally, the EBNA1 DNA binding function is essential for allknown EBNA1 functions, including genome maintenance, DNA replication,transcription regulation, and host-cell survival [Leight, E. R. and B.Sugden, EBNA-1: a protein pivotal to latent infection by Epstein-Barrvirus. Rev Med Virol, 2000. 10:83-100. Altmann M, Pich D, Ruiss R, WangJ, Sugden B, Hammerschmidt W. Transcriptional activation by EBV nuclearantigen 1 is essential for the expression of EBV's transforming genes.Proc Natl Acad Sci USA, 2006. 103:14188-93; Rawlins D R, Milman G,Hayward S D, Hayward G S. Sequence-specific DNA binding of theEpstein-Barr virus nuclear antigen (EBNA-1) to clustered sites in theplasmid maintenance region. Cell, 1985. 42:859-68; Ritzi M, Tillack K,Gerhardt J, Ott E, Humme S, Kremmer E, Hammerschmidt W, Schepers A.Complex protein-DNA dynamics at the latent origin of DNA replication ofEpstein-Barr virus. J Cell Sci, 2003. 116:3971-84; Schepers A, Ritzi M,Bousset K, Kremmer E, Yates J L, Harwood J, Diffley J F, HammerschmidtW. Human origin recognition complex binds to the region of the latentorigin of DNA replication of Epstein-Barr virus. EMBO J, 2001.20:4588-602]. Collectively, these studies demonstrate that EBNA1-DNAbinding domain is an ideal and validated target for inhibition ofEBV-latent infection and treatment of EBV-associated malignancies.

EBV plays a causative role in the tumorigenesis for a number of cancersincluding nasopharyngeal carcinoma, gastric carcinomas, non-hodgkinlymphoma (anaplastic large-cell lymphoma, angioimmunoblastic T-celllymphoma, hepatosplenic T-cell lymphoma, B-cell lymphoma, Burkitt'slymphoma, reticuloendotheliosis, reticulosis, microglioma, diffuse largeB-cell lymphoma, extranodal T/NK lymphoma/angiocentric lymphoma,follicular lymphoma, immunoblastic lymphoma, mucosa-associated lymphatictissue lymphoma, B-cell chronic lymphocytic leukemia, mantle celllymphoma, mediastinal large B cell lymphoma, lymphoplasmactic lymphoma,nodal marginal zone B cell lymphoma, splenic marginal zone lymphoma,intravascular large B-cell lymphoma, primary effusion lymphoma,lyphomatoid granulomatosis, angioimmunoblastic lymphadenopathy),leiomyosarcomas, X-linked lymphoproliferative disease, post-transplantlymphoproliferative disorders, Hodgkin's lymphoma and breast cancer. EBVhas been classified as a class I human carcinogen responsible for atleast 1% of all human cancer by the World Health Organization.EBV-associated malignancies account for more than 100,000 new cancercases each year in the United States. An inhibitor of EBNA1 would changecurrent clinical practice and be valuable for therapeutic treatment ofEBV-associated diseases. Currently, nucleoside analogues (aciclovir,ganciclovir, foscarnet) can be used to treat lytic EBV infection andpathologies related to lytic EBV infection. However, these generalanti-viral drugs are not specific for lytic EBV infection, and carry therisk of severe adverse effects. To date, no effective treatments existfor latent EBV infection, no treatment exists for pathologies related tolatent EBV infection, and no treatments exist for the treatment ofdiseases associated with EBNA1.

EBV infection and EBNA1 have also been implicated in infectiousmononucleosis [Henle W, Henle G. Epstein-Barr virus and infectiousmononucleosis, N Engl J Med. 1973. 288:263-64; Vetsika E K, Callan M.Infectious mononucleosis and Epstein-Barr virus, Expert Rev Mol Med.2004 6:1-16], chronic fatigue syndrome (CFS) [Watt T, Oberfoell S,Balise R, Lunn M R, Kar A K, Merrihew L, Bhangoo M S, Montoya J G.Response to valganciclovir in chronic fatigue syndrome patients withhuman herpesvirus 6 and Epstein-Barr virus IgG antibody titers.

Treatment with compounds that prevent EBV infectionwould provide therapeutic relief to patients suffering from infectiousmononucleosis, multiple sclerosis, systemic lupus erythematosus, andrheumatoid arthritis. Further, treatment with compounds that preventlytic EBV infection would provide therapeutic relief to patientssuffering from infectious mononucleosis, multiple sclerosis, systemiclupus erythematosus, and rheumatoid arthritis. Further, treatment withcompounds that prevent latent EBV infection would provide therapeuticrelief to patients suffering from infectious mononucleosis, chronicfatigue syndrome, multiple sclerosis, systemic lupus erythematosus, andrheumatoid arthritis. Treatment with compounds that inhibit EBNA1 wouldprovide therapeutic relief for suffering from infectious mononucleosis,chronic fatigue syndrome, multiple sclerosis, systemic lupuserythematosus, and rheumatoid arthritis. To date, however, no effectivespecific treatments exist for lytic EBV infection and no specifictreatment exists for pathologies related to lytic EBV infection. Inaddition, to date, however, no effective treatments exist for latent EBVinfection, no treatment exists for pathologies related to latent EBVinfection, and no treatments exist for the treatment of diseasesassociated with EBNA1.

There is a long felt need for new treatments that are bothdisease-modifying and effective in treating patients that are refractoryto current treatments for diseases and conditions associated with EBVinfection such as nasopharyngeal carcinoma, gastric carcinomas,non-hodgkin lymphoma, anaplastic large-cell lymphoma, angioimmunoblasticT-cell lymphoma, hepatosplenic T-cell lymphoma, B-cell lymphoma,Burkitt's lymphoma, reticuloendotheliosis, reticulosis, microglioma,diffuse large B-cell lymphoma, extranodal T/NK lymphoma/angiocentriclymphoma, follicular lymphoma, immunoblastic lymphoma, mucosa-associatedlymphatic tissue lymphoma, B-cell chronic lymphocytic leukemia, mantlecell lymphoma, mediastinal large B cell lymphoma, lymphoplasmacticlymphoma, nodal marginal zone B cell lymphoma, splenic marginal zonelymphoma, intravascular large B-cell lymphoma, primary effusionlymphoma, lyphomatoid granulomatosis, angioimmunoblasticlymphadenopathy, leiomyosarcomas, X-linked lymphoproliferative disease,post-transplant lymphoproliferative disorders, Hodgkin's lymphoma andbreast cancer. There is also a long felt need for new treatments thatare both disease-modifying and effective in treating patients that arerefractory to current treatments for infectious mononucleosis. There isalso a long felt need for new treatments that are both disease-modifyingand effective in treating patients that are refractory to currenttreatments for chronic fatigues syndrome. There is also a long felt needfor new treatments that are both disease-modifying and effective intreating patients that are refractory to current treatments for multiplesclerosis. There is also a long felt need for new treatments that areboth disease-modifying and effective in treating patients that arerefractory to current treatments for systemic lupus erythematosus. Thereis also a long felt need for new treatments that are bothdisease-modifying and effective in treating patients that are refractoryto current treatments for rheumatoid arthritis. There is also a clearand present need for the treatment of EBV infection, and there is a longfelt need for treatments that can specifically block lytic EBVinfection. There is a long felt need for treatments that can blocklatent EBV infection. There is also a clear and present need for newtreatments that are both disease-modifying and effective in treatingdiseases associated with EBNA1.

The present invention addresses the need to identify new treatments fordiseases and conditions associated with EBV infection such as infectiousmononucleosis, chronic fatigue syndrome, multiple sclerosis, systemiclupus erythematosus, and rheumatoid arthritis, and cancer, includingnasopharyngeal carcinoma, gastric carcinomas, non-hodgkin lymphoma(anaplastic large-cell lymphoma, angioimmunoblastic T-cell lymphoma,hepatosplenic T-cell lymphoma, B-cell lymphoma, Burkitt's lymphoma,reticuloendotheliosis, reticulosis, microglioma, diffuse large B-celllymphoma, extranodal T/NK lymphoma/angiocentric lymphoma, follicularlymphoma, immunoblastic lymphoma, mucosa-associated lymphatic tissuelymphoma, B-cell chronic lymphocytic leukemia, mantle cell lymphoma,mediastinal large B cell lymphoma, lymphoplasmactic lymphoma, nodalmarginal zone B cell lymphoma, splenic marginal zone lymphoma,intravascular large B-cell lymphoma, primary effusion lymphoma,lyphomatoid granulomatosis, angioimmunoblastic lymphadenopathy),leiomyosarcomas, X-linked lymphoproliferative disease, post-transplantlymphoproliferative disorders, Hodgkin's lymphoma, and breast cancer byidentifying novel EBNA1 inhibitors useful as therapeutic agents and intherapeutic compositions.

Procedures

The following procedures can be utilized in evaluating and selectingcompounds as EBNA1 inhibitors.

Inhibition of 5′-biotin-oPL4624 binding to His-EBNA1 using Alpha Screentechnology: Assays were performed using the DNA binding domain of EBNA1(amino acids 459-607), which was His-tagged (His-EBNA1) and theself-complementary biotinylated (bt) oligonucleotide with the sequence5′-bt-GGGTAGCATATGCTATCTAGATAGCAT-ATGCTACCC-3′ (bt-oPL4624). The proteinwas expressed in E. coli and purified according to Barwell, et al.(Barwell J A, Bochkarev A, Pfuetzner R A, Tong H, Yang D S, Frappier L,Edwards A M. (1995) Overexpression, purification, and crystallization ofthe DNA binding and dimerization domains of the Epstein-Barr virusnuclear antigen 1. J Biol Chem. 270: 20556-9.). The bt-oPL4624oligonucleotide was purchased from Integrated DNA Technologies, Inc(IDT). AlphaScreen donor, acceptor beads and white, opaque 384-wellassay plates were purchased from PerkinElmer, Inc.

Assays contained 15 nM His-EBNA1, 0.2 nM bt-oPL4624, 5 μg/mL AlphaScreenstreptavidin donor beads and nickel chelate acceptor beads, and a seriesof concentrations of test compound ranging from 3.2 nM to 100 μM in atotal volume of 40 μL assay buffer (25 mM Tris, pH 7.2, 160 mM NaCl, 1mM MgCl₂). His-EBNA1 (30 nM) and bt-oPL4624 (0.4 nM) were preincubatedwith 10 μg/mL nickel chelate AlphaScreen acceptor bead, or 10 μg/mLstreptavidin AlphaScreen donor bead, respectively, for 30 minutes atroom temperature in assay buffer. Twenty microliters ofHis-EBNA1/acceptor bead mix and bt-oPL4624/donor bead mix weretransferred to assay plates containing 0.44 of 1:3 serial dilutions oftest compounds previously prepared in DMSO at concentrations rangingfrom 0.32 μM to 10 mM. Nonspecific binding was determined with 5 μg/mLAlphaScreen acceptor bead in the absence of His-EBNA1. After 2 hrincubation at room temperature, the AlphaScreen signal was measured onthe Envision plate reader (PerkinElmer, Inc.) at 680 nm excitation and570 nm emission. Inhibition values at each concentration of testcompound were determined by setting 100% equal to raw data values in theabsence of EBNA1 and 0% equal to the raw data values in the presence ofEBNA1. Nonlinear regression fits of the inhibition values to a one-sitedose-response equation were performed using GraphPad Prism. Results fromscreening of representative compounds of the disclosure are described intable 6.

Cell based luciferase assay of EBNA1 inhibition: In vivo inhibition ofEBNA1 was determined for compounds of the disclosure using a cell basedluciferase reporter assay. EBNA1 binding to the Family of Repeat (FR)region is essential for EBV latent infection and host-cell viability,thus providing a physiologically meaningful cell-based readout. Aderivative of EBNA1, which is functionally equivalent to full-lengthEBNA1 and lacks the GGA repeats (90-325), was cloned intop3xFLAG-Myc-CMVTm-24 (Sigma-Aldrich Co., LLC) (N803). To make the assaymore sensitive by reducing the expression levels of EBNA1, the CMVpromoter was excised and the TK promoter inserted upstream of EBNA1. Toenhance the EBNA1-driven luciferase signal, the activation domain ofherpes virus VP16 (411-490) was fused to the C-terminus of EBNA1 usingSacII and BamHI restriction sites, resulting in the plasmidpTK-3xFLAG-Myc-EBNA1-VP16AD. Empty vector p3xFLAG-Myc-CMV-24 was used asa control. To create luciferase reporter plasmid, the FR region, a locusof 21 contiguous EBNA1 binding sites (7421-8042), was PCR amplified fromEBV genomic DNA and cloned into the pGLuc-Basic 2 (New England Biolabs)using the KpnI and HindIII restriction sites, resulting in plasmidpGLuc2-21xFR.

For the transient transfection assay, HEK293T cells were seeded at aconcentration of 4-8×10⁶ cells in a 10 cm plate in Delbecco's ModifiedEagle Medium (DMEM) (Life Technologies Corp.) supplemented with 10%Fetal Bovine Serum (FBS) (Gemini Bio-Products). After overnightincubation, the transfection was performed using Lipofectamine 2000(Life Technologies). 3 ug of pGLuc2-21xFR and 0.6 ug ofpTK-3xFLAG-Myc-EBNA1-VP16AD or p3xFLAG-Myc-CMV-24 (empty vector) wereadded to 0.5 ml Optimem buffer (Life Technologies Corp.). 30 ulLipofectamine was added to a separate 0.5 ml Optimem buffer andincubated for 5 minutes. The DNA and lipofectamine mixtures werecombined and incubated for 20 minutes at room temperature and added dropwise to the 10 cm plate. The cells were then incubated for 6 hours at37° C. The cells were harvested, counted and re-suspended at aconcentration of 2×10⁵ cells/ml and distributed using a MicroFlodispenser (BioTek) in 384-well tissue culture plate (Greiner BioOne), 40ul (8000 cells) per well. 160 nl of solutions of compounds of thedisclosure in DMSO at concentrations ranging from 50 mM to 976 uM wereadded to the cells (10-point 2-fold dilution series, final concentration200 uM-390 nM) using a Janus modular Nanohead dispenser (PerkinElmer,Inc.). Compounds and transfected cells were incubated overnight at 37°C. Gaussia luciferase is secreted into the medium. The top 10 ul of cellmedia from the 384-well transfected HEK293T cells is transferred to awhite opaque 384-well development plate. 10 ul of substrate is added toeach well and incubated for 5 minutes. Bioluminescence is then measuredusing the Envision Multiplate Reader (Perkin Elmer, Inc.). To normalizethe activity of the compounds of the disclosure and to filter toxiccompound, the remaining 30 ul of cell media (including the cells) areincubated with 6 ul resazurin, incubated for 4-6 hours at 37° C. andmeasured using the Envision Multiplate Reader.

Cell Viability Assay: To further evaluate the cell-based efficacy ofEBNA1 inhibitors, a cell cytotoxicity assay was performed. EBNA1inhibitors should selective kill EBV-positive cell lines (Raji, LCL,C666-1) relative to EBV-negative cell lines (Bjab, DG75, HNE-1). Raji,Bjab, and DG75 were obtained from American Type Tissue Culture (ATCC),C666-1 and HNE-1 were a gift from Anne Lee (Hong Kong University) andthe Lymphoblastic Cell Line (LCL) was obtained by in vitro infection ofB-cells with the B95.8 strain of EBV.

To perform this assay, 40 ul of the different cell lines were seeded ata concentration of 1×10⁵ cells in a clear 384-well plate (4000cell/well). 160 nl of compound at concentrations ranging from 50 mM to976 uM were added to each well (10-point, 2-fold dilution series, finalconcentration 200 uM-390 nM) using a Janus modular Nanohead dispenser(PerkinElmer, Inc.). Cells were incubated for 72 hours in a humidified37° C. incubator 5% CO₂. The cell viability is inferred using theoxidation-reduction indicator, resazurin. 8 ul of resazurin was added toeach well and after 4-6 hours incubation at 37° C., the fluorescentsignal was monitored using 530-560 nm excitation wavelength and 590 nmemission wavelength using the Envision Multiplate Reader.

Data analysis and CC₅₀ (Cytotoxicity Concentration) curves are generatedusing Prism (GraphPad). A selectivity index is calculated by determiningthe ratio of the CC₅₀ from the EBV-negative cell line over the CC₅₀ fromthe EBV-positive cell line.
